Over the past month, we’ve noticed an uptick in letters informing us that GM’s new 3.0L Duramax engine for the 2019 Silverado 1500 and Sierra 1500 had been delayed, supposedly due to issues associated with emissions testing. We are not aware how this rumor started, but we looked into it – and got some answers.
First things first: GM initially announced that it will launch the all-new 3.0L Duramax inline-six in its all-new, half-ton pickup trucks during the first half of the 2019 calendar year. Given that we’re writing this in February, The General still has a few more months – until June, in fact – to launch the new engine, to fit into its own time frame. But that’s not all.
“We had said it would be early 2019, and we are on track,” Chevy’s Monte Doran told us via email. “We will share more information about the engine once we have our final testing and fuel economy certification complete,” he added.
So, there you have it – rumors that the GM 3.0L Duramax has been delayed are false.

The only official details GM has shared about the new 3.0L Duramax I6 are these:
GM hasn’t shared power and fuel economy figures whatsoever, but an unofficial leak last October pegged the new 3.0L Duramax as making 282 horsepower and 450 pound-feet of torque, while achieving 28 MPG on the highway and tow up to 7,800 pounds. Those numbers could be spot on, or could be totally off. We’ll have to wait for the official announcement from GM to be sure.
For now, all we know for sure is that GM is on track to introduce the highly-anticipated 3.0L Duramax diesel in its half-tons in the first half of the year.

Can't wait to see this in the GMC. People seem to be forgetting that we still have this exciting engine to look forward to, should whip the V6 Powerstroke since it's purpose built and a straight 6.
It's great to see all the auto manufacturing investments coming back into the U.S. Great to see companies not only design cars and trucks in the U.S. but actually make them here using great American workers. GM is a little behind in re-investing in the U.S. compared to Ford and others, but let's hope they see the importance of supporting American workers and communities.
Appreciate the sentiment but gm is not a little behind. They are going in reverse, fast! Closing US plants and laying off many thousands of workers at HQ. Meanwhile investing in new products built in China and Mexico. GM insists they are no longer a car company. I'd say they are no longer American either. Globalism is suicide
Well, I'd hope you are right, but if the 7800 pound towing limit is right, then GM is once again, woefully uncompetitive. I believe the F150 diesel is around 10,000 pounds.
What I'd really like to see is the 3.0 put in the 2500HD. Not everyone needs 900+ foot pounds of torque, or wants to pay for what they will never use.
I don't get the tow rating sentiment. Have you towed 10K with an F150 3.0 diesel? The rating means nothing when it's anemic doing it or the truck itself is overloaded at the hitch. The number war is strictly to sell based on having a bigger number. Ford is marketing you specifically.
Will this truck run better than the 2016 diesel dually we purchased? Yeah- $68000 to repair a fuel pun that EXPLODED in our truck! No recall no NOTHING! I read on this page that the fuel pump installed on the truck was for European vehicles, not American and the company KNEW it would falter and used it ANYWAY!!!!! I spy $1030 a freakin month for a truck that’s a piece of crap! Rest assured- I WILL BE TRADING IN MY HINK OF JUNK and purchasing elsewhere!
Too bad your quality of vehicles has gone down the toilet! My 2007 Yukon Denali ROCKS! 290,000 and still kicking it and looking GREAT! Shame on your company! I’ll be jumping on that class action lawsuit!
Fingers crossed that the next generation 2020 Chevrolet Suburban, Tahoe, and GMC Yukon/Yukon XL will be available with this powertrain.
Not just avalable in these vehicles but it must be class leading across the board. I am tired of seeing GM being late to the game and still not measuring up to the competition.
I think it's very good that GM builds the diesel engine as 3.0 inline six. V6 engines are good but costly and expensive in production and maintenance.
Info: BMW built so far no V6 engines? Mercedes, Landrover and now GM build 3.0 diesel engines as inline six. Previously, these manufacturers built elaborate and expensive 3.0 V6 diesel. Even for multiple charging, the Inline Six engine is better. See BMW with the 3-way or 4-way turbocharger engines in the M550d, M750d, X5 50d and X6 50d.
Also GM could do this, because for small SUV and pickup technically demanding 3.0 I6 diesel and 3.0 I6 gas engines are perfect. Developed and produced in the US for customers worldwide.
Has anyone kept up with the sales of the diesel engines in the Ford and even Ram? I was wondering how the Ford was doing since it released. I think we could see class leading power and torque (mostly torque) of the three diesel engines, but class leading payload and towing I don't know since the Ford already has 1000lbs more towing capacity. I know they went for the good in all categories but I wished they were better in most.
GM is number one in sales of the big three, they are also the most profitable (fact that is well documented). Cars produced in Mexico are leas costly to build and are getting higher quality ratings. GM's top quality ratings are coming from Mexico not the unionized American employee. GM is running the business to be lean and efficient, they are not going to run factories at less than 70%. GM also has made it clear their focus is a good quality product and being profitable. Every day in America companies lay people off and eliminate jobs, the leaders of all companies make these decisions daily. The unions should focus on unionizing Toyota, Tesla and all other non union companies. Instead the unions beat up their bread and butter companies with threats, and trying to hurt the company. These old school tactics that will no longer work and will cause more layoffs. Even Walmart has laid off thousands of workers and closed many stores in 2018, this is called running the business to keep viable.
Again GM is number one in vehicle sales in the United States and Globally of the big three car companies, GM is also the most profitable of the big three, they also employ the most workers in the united states of any car company (fact that is well documented).
Just not any of those statistics apply to Canada , like they once did. They are shooting to be the smallest employer in the automotive industry here and the public is upset with this company. How many vehicles do Mexicans buy vs. Canada.
Not delayed? Yeah right....Where are they? Why have orders been cancelled?
